Rebuilding the installer would then modify the .discinfo and .treeinfo
of the install and it would make that ISO not work against any normal
CentOS tree.  It then is no longer CentOS and you can't distribute that
as CentOS.  Fairly simple.

If you want to rebuild an installer and redistribute something, that is
what SIGs are for.  Community reviewed and agreed upon process, produced
on the official CentOS Community Build System.  It can be called CentOS
and the entire process will be completely open and available to all SIGs
that need them.  It will also be approved by the CentOS Board.

So, yes, if you change the directories that make it CentOS, respin those
parts of the ISO (ie, change the installer parts, the treeinfo and
discinfo), and try to redistribute that then it is not CentOS.

If, on the other hand, you take a minimal install ISO, leave all the
original pieces alone, add other stuff to it that is additive only, then
it is your thing on top of CentOS as a kickstart to happen after the
CentOS install .. and you can call it 'Your Thing' on CentOS.  But you
can't call that just CentOS .. it is 'Your Thing' on CentOS.
